Copy the full path of a file to the clipboard (requires xclip or similar)
Handy for those times you need to paste a file path in an IDE or some other app. sudo apt-get install xclip Then, for convenience, alias xclip to 'xclip -selection c' so you can just do something like realpath . | xclip

to include hidden dirs use: $ tree -adL 1 (with ls, requires 'ls -ad */ .*/')

This works just as well for SMTP. You could run this on your mail server to watch e-mail senders and recipients: tcpdump -l -s0 -w - tcp dst port 25 | strings | grep -i 'MAIL FROM\|RCPT TO'
